To those getting less than stellar battery life,

Keep in mind that anything using location services drains the battery more quickly. Also games. And if you get 20 emails an hour pushed to your inbox, well, you get the idea.
 
42%

Usage: 4 hours, 38 mins

Standby: 15 hours, 49 mins

Email getting pushed to me too

I'm extremely happy with my battery. Much better than my 4. It's also getting better by the day.
 
OK, now I know some people say it makes no difference due to the battery type so I can only speak from peronal experience, BUT, I was concerened about my battery life on my iPhone 5 as it was draining way too fast for my liking. I was quite prepared to do a full 'as new' restart but first thought I'd try the drain-fill-it-up-again method to calibrate...something.

I don't know what this process calibrated (if anything), be it battery or software, but for me at least it has rectified the problem.
Rather than drop by 1 percent each time I unlock it and load Safari it has stayed a constant 100% since I unplugged it 2 hours ago, which may not seem impressive to some but has definitely made a difference to the performance I have been getting.

I'm not advocating this as a fix for everyone's battery problems (I have also turned off pretty much all the location services apart from the ones I know I use and a lot of the settings that are switched on that I know make no real difference) but it is worth a shot.

I'm aware that there are nay-sayers whom claim that this has no benefit in regards to the battery type in the phone and whilst I don't know enough about the battery type to present an argument to say that it does I can say that it has caused something in there to make me far happier!

Hope this helps someone.
 
if you're getting crap battery life and haven't done the following, best to do it:

start from scratch. do NOT restore from a backup. most battery drain issues are due to users restoring from their backup.

limit the amount of apps you have on your device. i only have a handful of apps and ensure the apps are not constantly using data

set phone to manual brightness and at around ~15% brightness

make sure to use WiFi whenever possible.

After yesterdays woes (losing 40% on train journey to work) I did the following

a) Reset all settings (not content)
b) Turned off location services for all apps that I can do without

Today, I have lost only 15% in 3 hrs, so it looks like I am back to iphone 4 performance
 
Lab Tests: How long does the iPhone 5's battery last?

http://www.macworld.com/article/2010535/lab-tests-how-long-does-the-iphone-5s-battery-last.html


Given some of the iPhone 5’s other improvements—thinner body, larger screen, and greater number of pixels to illuminate—it wouldn't seem that the new phone could also match, much less exceed, its predecessor's battery life. And, in fact, it doesn't, though it comes close.
Apple has claimed that the iPhone 5 would deliver “up to 10 hours” of video playback on a single charge—the same as the 4S. To see how good the new iPhone's battery life really is, I ran it through our standard battery test and then compared the result to those of the iPhone 4S, and iPhone 4; for good measure, I also compared it to the third-generation iPad and iPad 2.
More specifically, I first updated those older devices to iOS 6. I then took a luminance meter and set the screens of all of the devices to 200 nits. I turned off Auto-Brightness and put each device into Airplane mode. Lastly, I set the volume two clicks up from its lowest setting. Then, with the same 120-minute video playing at fullscreen on repeat, I timed each device to see how long it would take to drain the battery and power off.
Results are in hours:minutes. Longer bars are better. The results: Simply put, the iPhone 5 did not last as long as the iPhone 4s or 4. It lasted 8 hours and 21 minutes—about 6 percent less than the iPhone 4S and about 4 percent less than the iPhone 4. Compared to the two current iPads (which have much bigger batteries), the iPhone 5 lasted 27.5 percent less time than the iPad 2 and 17 percent less than the third generation iPad.

I'm sorry but restoring from backup does not affect your battery life at all.
 
No apple said 8hrs screen on time with LTE browsing the whole time?

There's often a difference between what a company says and what actually happens in the real world. Apple says my iPad would last 9 hours of use, in reality it lasts no more than 5.
 
I got 3 hours and 31 minutes use and 12 hours exactly on standby before my battery died (100% down to 0%) is that good or should I worry? It feels like I didn't use it as much as I did my iPhone 4S but it died sooner
 
mine is holding up pretty good. i charged it in the night from saturday to sunday.

i got 7 hours of usage, 2 days and 4 hours standby and still 65% :eek:
 
Mine has been mixed, seems to be good, then seems to die quickly.
I did find one issue, iheartradio is crushing the CPU and battery, started with approx 50% battery, streaming iheartradio the phone was dead in about 2 hours and very warm to the touch.

I use Sysstats lite to monitor the phone, with no apps running I am at about 2% CPU usage. With iheartradio the usage jumped to >50%. For comparison, Pandora is running at 10% usage.

here are screen caps from the last two days. Have LTE turned off as it is not yet available here. Some location services on, push email on, some icloud services on.

i think I got a good battery....

at 38%

Usage: Amount of time iPhone has been awake and in use since the last full charge. The phone is awake when you’re on a call, using email, listening to music, browsing the web, or sending and receiving text messages, or during certain background tasks such as auto-checking email.
Standby: Amount of time iPhone has been powered on since its last full charge, including the time the phone has been asleep.

this is more like what I have, around 4 hours if you stream media (audio /video)
 
I'm going to monitor this thread because I just switched from an HTC Thunderbolt to an S3 and the battery life is really bad..better with rooting and tweaking, but still bad.. I'm considering returning my S3 and getting the IP5, or I might switch back to the TBolt.. kinda have buyers remorse (phone is great, but doesn't seem worth the full $ I paid for it since I am keeping unlimited data on VZ).

Edit: I've been off charger for 5 hours and at 79%. I played some music for about 20 min and did 20-25 min of browsing (mostly twitter/fb reading).

not good for me

As you can see standby for nearly 4 hours.

I did not use my phone for 18 minutes. Actually I didn't use it at all other than to take this picture (it was in my bag while I worked out). I received about ten emails according to my alerts, but I didn't check any (all received before i even unplugged it).

Woke up, I unplugged it, put it in my bag, got to work, couldn't believe my eyes.

My iphone 4 would have been at 99-100%.

Other:
LTE - off
wifi - off
bt - off
4g - on
email - push (gmail)

I don't understand.

Looks to me that you have plugged it in since the last full charge.

Since I'm at exactly the same percentage you just posted I took a look at my usage to compare. I'm at 95% with 3 hours, 41 minutes standby and 59 minutes usage. However I actually have been using my phone during that time and really have done quite a lot (searching for and downloading apps, web browsing, texts, some Siri). I've been seeing quite a few posts stating that the person hadn't even used their phone at all since unplugging it from the charger, yet there will be usage recorded. :confused:

I have LTE turned off. And yesterday battery life seemed good. I unplug the phone this morning, read the news and listen to a news podcast and I'm at 87% already?!?
 
Bwhaha... I love all the people who post screen shots of like 8 or more hours of usage time, with battery life left, saying "LOOK AT THIS!!! SO GOOD!!!" but then below their usage stats it mentions the phone has been plugged in between charges. lol

Seriously people, think will you.
